furby

What do you get if you cross a Furby with a master of 20th Century literature? The Borgy. Argentinian hacker [Roni Bandini] found an old Furby and decided to hack it by altering its personality. His inspiration was the Argentinian writer Jorge Louis Borges, one of the pioneers of surrealist writing. The idea is that, at random times during the day, the Borgy will share a bit of wisdom from Borges to inspire and enlighten.

[Roni] hacked the Furby to replace the speaker with a more powerful one, and built a base to hold the larger speaker and a switch which can activate Borgy. He also used an Arduino Nano and a Sparkfun MP3 player shield loaded with the samples of Borges.

When the Furby speaks, it shares some wisdom from Borges. It’s a simple, but a surprisingly effective hack that could be very useful for someone seeking inspiration. Or, as Borges himself once said: “Don’t talk unless you can improve the silence.”

Falling into the marvelous space between, ‘I really want to do that’ and ‘but that’s a lot of work and I’m lazy’ comes this reproduction of the motherboard from the original IBM 5150. This is a complete reproduction of the first PC, being sold as a kit. Yes, chips are included, although I highly doubt they’ve gone through the trouble of finding chips with contemporaneous date codes. We’re dying for a writeup on this one.

Someone has found the source code for the first Furby. [Mark Boldyrev] was talking with a few fellows on the MAME forum to see if anyone had the source for the Furby. He was looking into contacting the USPTO for the original source but the red tape involed was a bit too intense. Luckily, that research turned up some info from [Sean Riddle] who somehow already found the original source listing. After [Mark] got in contact, [Sean] posted it as a PDF. Yes, it’s 6502 source, although the microcontroller is technically a SPC81A, with the rest of the hardware consisting of TI50C04 speech chip. (you would not believe how many toys are still shipping with a 6502-ish core somewhere inside). The files are up in the archive, and we’re probably going to have a Furby MAME sometime soon.

The Bitfi hardware wallet is a cryptocurrency storage device being bandied about by [John McAffee], and there’s a quarter million dollar bug bounty on it. It’s ‘unhackable’, and ‘it has no memory’. I’m serious, those are direct quotes from [McAffee]. Both of those claims are nonsense and now it can play Doom.

Oh noes, a new hardware backdoor in x86 CPUs! [xoreaxeaxeax] has published a demo that allows userland code to read and write kernel data (that’s very bad). The exploit comes in the form of the ‘rosenbridge backdoor’, a small embedded processor tightly coupled to the CPU that is similar to, but entirely different from, Intel’s ME. This processor has access to all the CPU’s memory, registers, and pipeline. The good news, and why this isn’t big news, is that this exploit only affects Via C3 CPUs. Yes, the other company besides Intel and AMD that makes x86 CPUs. These are commonly found in industrial equipment and ATMs.

Sometimes you have an idea that is so brilliant and so crazy that you just have to make it a reality. In 2011, [Look Mum No Computer] drew up plans in his notebook for a Furby organ, an organ comprised of a keyboard and a choir of Furbies. For those who don’t know what a Furby is, it’s a small, cute, furry robotic toy which speaks Furbish and a large selection of human languages. 40 million were sold during its original production run between 1998 and 2000 and many more since. Life intervened though, and, [LMNK] abandoned the Furby organ only to recently take it up again.

He couldn’t get a stable note out of the unmodified Furbies so he instead came up with what he’s calling the Furby Forman Fusion Synthesis. Each Furby is controlled by a pair of Ardunios. One Arduino sequences parts inside the Furby and the other produces a formant note, making the Furby sing vowels.

We love the label he’s given for what would otherwise be the power switch, namely the Collective Awakening switch. Flicking it causes all 44 (we count 45 but he says 44) Furbies to speak up while moving their ears, eyes, and beaks. Pressing the Loop switch makes them hold whatever sound they happen to be making. The Vowel dial changes the vowel. But you’ll just have to see and hear it for yourself in the videos below. The second video also has construction details.

The original Furby product wowed consumers of the 90s. In addition to animatronic movements, it also packed simulated voice learning technology that seemed to allow the Furby to learn to speak. It wasn’t like anything else on the market, and even got the toy banned from NSA’s facilities in case it could spy on them. Elegantly, the robot uses only one motor to move all of its parts, using a variety of plastic gears, levers, and cams to control all of the robot’s body parts and to make it dance.

Over the past twenty years the Furby has earned the reputation as one of the most hackable toys ever — despite its mystery microcontroller, which was sealed in plastic to keep the manufacturer’s IP secret. [Zach] replaced the control board with a Pi Zero. He also replaced the crappy mic and pizeo speaker that came with toy with a Pimoroni Speaker pHat and a better mic.

Long before things “went viral” there was always a few “must have” toys each year that were in high demand. Cabbage Patch Kids, Transformers, or Teddy Ruxpin would cause virtual hysteria in parents trying to score a toy for a holiday gift. In 1998, that toy was a Furby — a sort of talking robot pet. You can still buy Furby, and as you might expect a modern one — a Furby Connect — is Internet-enabled and much smarter than previous versions. While the Furby has always been a target for good hacking, anything Internet-enabled can be a target for malicious hacking, as well. [Context Information Security] decided to see if they could take control of your kid’s robotic pet.

Thet Furby Connect’s path to the Internet is via BLE to a companion phone device. The phone, in turn, talks back to Hasbro’s (the toy’s maker) Amazon Web Service servers. The company sends out new songs, games, and dances. Because BLE is slow, the transfers occur in the background during normal toy operation.

Furbys have been around for a while and they are an interesting (if annoying) toy that will teach the kids to be okay with their eventual robotic overlords. In the meantime, the latest version of the robotic companion/toy/annoyance uses Bluetooth LE to communicate with the owner and [Jeija] has been listening in on the Bluetooth communication, trying to reverse engineer the protocol in order to run code on Furby.

[Jeija] has made a lot of progress and can already control the Furby’s actions, antenna and backlight color, and change the Furby’s emotional state by changing the values of the Furby’s hungriness, tiredness, etc. [Jeija] has created a program that runs on top of Node.js and can communicate with the Furby and change its properties. [Jeija] has also discovered, and can bring up, a secret debug menu that displays in the Furby’s eyes. Yet to be discovered is how to run your own code on the Furby, however, [Jeija] is able to add custom audio to the official DLC files and upload them into the Furby.

[Jeija] points out the all this was done without taking a Furby apart, only by sniffing the Bluetooth communication between the robot and the controlling app (Android/iOS device.) Check out a similar hack on the previous generation of Furbys, as well as a replacement brain for them. We just hope that the designers included a red/green LED so that we will all know when the Furbys switch from good to evil.

One of the classics of circuit bending is to mess around with the clock chip that drives the CPU in simple noise-making toys. [Goran] took this a step further with his Furby hack. Skip down to the video embedded below if you just want to see the results.

After first experiments modifying the Furby’s clock with a string of resistors (YouTube), [Goran] decided to opt for more control, overriding the clock entirely with a square wave coming out of an Arduino. And then, the world became his oyster.

The Furby’s eyes were replaced with ultrasonic distance sensors, and what looks like a speaker was hot-glued into its mouth. Since this particular Furby only “talks” when you pull its tail, he naturally wired in tail-switch control to boot. As [Goran] suggests, a light show is the obvious next step.

If you haven’t pulled apart an electronic toy and played around with glitching it, you don’t know what you’re missing. We’ve got a classic intro to circuit bending, as well as projects that range from the simple to the ridiculously elaborate. It’s a fun introduction to electronics for the young ones as well. Grab a toy noisemaker and get hacking.
